Boric sludge light through hole ceramsite

Abstract

The invention discloses boric sludge light through hole ceramsite. According to the technical scheme, the boric sludge light through hole ceramsite is characterized by being composed of boric sludge, viscous attapulgite clay, powdery boric sludge foaming agent, activated clay waste residues, floating beads, light magnesium oxide, expanded perlite, expanded vermiculite and ferrous sulfate; the ingredients of the boric sludge light through hole ceramsite are stirred, mixed, extruded, granulated, dried, calcinated, warmed and screened and then sealing and packaging are performed to obtain the boric sludge light through hole ceramsite. The boric sludge light through hole ceramsite has the advantages that the specific surface area is large, the stacking density is small, the water absorption rate is high, the gas permeability is excellent, the appearance molding is attractive, no peculiar odor exists, no harmful bacteria exist, the weight is light, the strength is good, and microholes and large holes are integrated. When the boric sludge light through hole ceramiste is used for cultivating or planting various nursery stock, flowers, grass and vegetables, the roots of the plants will absorb nutrient ingredients of liquid fertilizer or water from the boric sludge light through hole ceramsite, it is ensured that plants grow and develop well and the survival rate is high, and the boric sludge light through hole ceramsite is applicable to preparing soilless culture substrates and nutrient soil.

Description

technical field [0001] The invention relates to ceramsite, in particular to a boron mud lightweight through-hole ceramsite. Background technique [0002] The soil used for cultivating or planting various seedlings, flowers and vegetables is mostly made of nearby soil, and then mixed with some plant ash or peat soil. The moisture content of these soils is 12-20%, and contains a large amount of harmful bacteria. [0003] When using these soils to cultivate or plant various seedlings, flowers and vegetables, it is difficult to control the amount of water in the later stage. After water replenishment, the soil moisture content exceeds 30%, and the moisture content in the soil is relatively high, and the soil will be semi-fluid. If the soil is not replenished in time, the soil will appear compacted and hard, which will directly affect the normal growth of plants. [0004] With the continuous improvement of the quality requirements of greening projects, materials such as fly ash...

Problems solved by technology

[0013] The stockpiling and disposal of boron mud not only occupies a large amount of land, but also alkalizes the soil near the stockyard and causes the migration and transformation of boron. Where the boron mud is discharged, no grass will grow, and its lye can dissolve into the groundwater, making the surrounding The production of farmland is reduced, and severe cases can cause crops to fail, and pollute the surrounding drinking water

Due to the fine particles of boron mud, after losing moisture, it will often scatter with the wind, causing pollution to the atmospheric environment
